The invention relates to a process for preparing a ceramic paste for dental prosthesis keeping an identical coloration after firing. It consists in combining of the preparation of the ceramic powder freed from its organic colorants with a liquid having a refractive index corresponding to that of the ceramic and allowing light to pass through without distorting the perception of the exact coloration, which will be kept identical after firing. It results in enabling a practitioner to determine, when making the ceramic paste which is ready to be modelled for the making of false teeth, crowns or other prostheses, the exact coloration the product will possess after firing. |
